COMBINATION-TOOL.

I SPECIFICATION forming part of Letters Patent No. 643,825, dated February 20, 1900;

Application filed November 13, 1899. $eria11lo.'736,895. (N0 model.)

T0 all whom, it may concern:

Be it known that I, MAXIME GUALBERT LAMBERT, asubject of Her Majesty the Queen of GreatBritain, residing at Kateville, county of Stanstead, Province of Quebec, Canada, have invented certain new and useful Improvements in Combination-Tools; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to combination-tools; and one object is to provide a tool of this kind in which are combined several implements especially useful for the purpose of tapping sugar-maples.

A further object is to provide a combination-tool which will combine several different implements in a simple and efiective manner and one which will be manufactured at a low cost.

To these ends the invention consists in a combination-tool constructed substantially as hereinafter illustrated and described, and defined in the appended claim.

Referring to the drawings, Figure I illustrates a plan view, partly in section,-of the improved combination-tool. Fig. 2 is a top view of the ax-head.

One of the great inconveniences encountered by operators in the sugar-bush is the necessity of carrying the number of difierent tools used in the business, which are, moreover, liable to drop in the snow and get lost. To overcome these inconveniences, I have provided the tool shown in the drawings, in which A represents a small ax or hatchet which may be of any ordinary or preferred construction. The face of the ax is provided back of the cutting edge with a suitable socket a, which is designed to receive the shank of a removable bit ct, which may be of any preferred construction best suited to the intended purpose. A binding-screw a is mounted in the aX-head and is adapted to engage the shank of the bit a to secure the same in its operative position. The aX-handle is of the usual construction, encept that it is preferablyof somewhat greater curvature than the ordinary handle, and at its lower end is mounted the handle-grasp B of an ordinary drillbrace,which is rotatably mounted on the end of the shank b, which engages a suitable socket 1), formed in the end of the ax-handle. A suitable leaf-spring b is secured within the socket b and is provided with a button b which projects through a slot 12 in the side of the handle, by means of which the spring may be released from a notch 6 formed in the end of the shank b. By this constructionthe hand'grasp B may be readily attached to and removed from the handle and yet be securely held in position by means of the spring engaging the notch in said shank.

The position of the bit a with respect to the hand-grasp B is such that by revolving the ax-handle the tool operates as an ordinary brace-bit, and can thus be readilyutilized to bore holes in the trees for the sap-plug. The bit a,being removably secured in the ax-head, may be readily replaced when broken by a new one,or different sizes of bits may be used, or different tools-such as a saw, &c.utilized instead of the bit, if necessary, as is obvious.

The hammer end D of the ax is provided with a recess (1 at its upper end, having an undercut groove or mortise d in the bottom thereof. A sliding block D is adj ustably mounted in said recess d by means of a tenon d which engages the said mortise d. A threaded perforation d is formed vertically through said block, and a threaded operatingrod D engages said perforation and passes down through the lower portion of the hammer-head and is rotatably fixed therein, by means of which the block D may be moved up and down in the recess 61. As the block D is moved upwardly a space (1 is formed between the lower face of said block and the aX-head, which may be utilized as a wrench to engage and remove a nut. &c. The space (1 may be varied in width to fit several sizes of nut by simply turning the operating-rodD Below the sliding block D the ax-head is recessed, as at O, and a filling-block C, of wood or other suitable material, is inserted within said recess and held in place by the threaded rod D which passes therethrough. This filling-block C is useful for driving the sap-plugs into position in the holes bored by the bit a, the comparatively soft and elastic face of said block preventing injury to the said plugs, which are usually of wood.

I claim- A combination-tool, comprising an ax, hav- [5 ing a bit-socket formed in the upper edge of the head, a bit removably secured therein, and a hand-grasp secured upon the extremity of the ax-handle, substantially as described.

In witness whereof I have hereunto set my 20 hand in the presence of two witnesses.

MAXIME G UA LBERT LAMBERT.

Upon the under side of the ax-head, near the cutting edge, is formed a groove E, having bevelededges and which is adapted to remove the tap-plugs when necessary.

\VhileI have herein shown a preferred form of carrying my invention into efiect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within Witnesses:

WILLIAM B. ROBERTS, R. A. DE OLLOGUI.
